Title: Improvements in or relating to fluid reaction flying controls for aircraft
Inventor: METTAM ALBERT RONALD
IPC: B64C21/02
Filed: 1950-06-09
Abstract: 703,067. Controlling aircraft. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 31, 1951 [June 9, 1950], No. 14392/50. Class 4 An aircraft flying control system comprises a duct which connects an outlet opening at the surface of an aerofoil with a forwardly directed intake which opens at or in advance of the leading edge part of the aerofoil so that air entering the intake in consequence of forward motion ot the aircraft issues trom the outlet and so produces a control force. In Fig. 6, the wing 50 comprises a pair of ducts 51, 52 which terminate in intake apertures in the wing leading edge and outlet apertures in the upper and lower surfaces. The intake apertures have pivoted closures 53, 54 and the outlet apertures sliding closures 55, 56. A mechanism for opening the closures, described for the duct 52 but applicable to both ducts, comprises a three-arm lever 57 fulcrumed about a vertical pivot 58 and having two opposed arms. connected by links 59, 60 with the intake and outlet closures 54, 56 respectively. A spring 61 holds both closures shut and an arm 63 on the three-arm lever is connected to an operating rod 62 which terminates adjacent a lever 64 mounted on a pivot 65 and connected by links 66, 68 and a pivoted lever 67 to a pilot's control column 69. A pivoted lever 71 having an extremity located in opposition to the end of the link 62, is connected by a rod 70 to the mechanism for operating the closures 53, 55. The closures normally maintain the continuity of the wing surface but lateral movement of the control column 69 in either direction will cause the closures 53, 55 or 54, 56 to open simultaneously to permit a flow of air through the ducts 51 or 52 to create a lateral control force. The ducts may be positioned side by side as shown or one above the other, Fig. 4, (not shown). In Fig. 8, the rear end of the fuselage 88 is surrounded by a cowl 87 having a forwardly directed annular intake and a rearward outlet which carries a closure 91. The ducts 81, 82 in the tail surfaces 89. 90 are connected to outlets 83, 84 and the intakes are closed by sliding closures 92, 93. In normal flight the closures 91, 92, 93 are located in the positions shown by dotted lines but when a controlling force has to be exerted the closure 91 is moved to its full-line position and the appropriate closure 92, 93 opened simultaneously. The outlets 83, 84 may have closures operatively connected with the closure members 91, 92, 93. According to the Provisional Specification, the device may be combined with normal control surfaces and trimming of the aircraft may be effected by displacement of one or more control ducts closures or by means of small auxiliary ducts and a gust detector may be associated with the device in order to increase or decrease the overall lift on a wing.

Title: Improvements in or relating to tubular heat-exchangers
IPC: F28F1/02
Filed: 1944-07-28
Abstract: 581,038. Tubular heat-exchangers. BRISTOL AEROPLANE CO., Ltd., OWNER, F. M., and ROBERTS, L. M., and ROBERTS, R. A. (Representatives of ROBERTS, L. C.). July 28, 1944, No. 14469. [Class 64 (iii)] A heat-exchanger, e.g., for the gas turbine plant of an aircraft, comprises involute or other shaped rows of flat-sided straight tubes 12, Fig. 1, disposed within a cylindrical casing, the ends 14, Fig. 5, of the tubes being slotted and bent outwards in an arcuate or parabolic curve so that the tubes in each row and the tubes in adjacent rows may be welded together along the edges 13 and 14a respectively. The triangular spaces between the casing and the ends of the rows of tubes are sealed by a grooved ring 15, Fig. 6, having triangular parts formed with lips 17 adapted to be welded to the end tubes of the rows, and curved ridges 18 welded to the edges 14a. By this arrangement, the usual tube-plates are dispensed with and the arcuate or parabolic connections between the tubes in adjacent rows allow for relative expansion. In use, one fluid passes through the tubes while another flows through the passages 20 between the rows from the circumference of the casing to a central collector 11 and thence back to the circumference. In a modification, the tubes are of trapezoidal cross-section and the ends are machined so as to remove three sides thereof and leave one side which is bent over to form the arcuate connection between the tubes in adjacent rows.

Title: Improvements in or relating to rotary printing presses
IPC: B41F27/12
Filed: 1935-05-17
Abstract: 456,902. Printing surfaces and apparatus. WALE, B., 734, Mather Street, Chicago U.S.A. May 17, 1935, No. 14520. Convention date, March 28. [Class 100 (ii)] An etched sheet metal typographic printing plate adapted for use on a rotary press is formed of material of thickness of the order of À008 inches, both the relief printing portions and the non-printing portions being of uniform thickness, and that of the former being not more than twice that of the latter, so that a plate is obtained which is sufficiently thin and flexible to conform to a cylindrical carrier and is sufficiently strong to be held thereon under tension. The plate 1, Fig. 2, is preferably of zinc or copper and is etched in the non-printing areas to a depth of À002 to À004 inches. Margins 3, and if desired bands 2<a> along the edges, are left of undiminished thickness, the margins being bent along etched lines 4 to form end channels 6, 7, Fig. 1. The printing roller 8 which may be small, particularly when used for printing billheads or the like, is formed with a groove 9 in which the nested channels 6, 7 of the plate are secured by a clamping bar 10, attached to the cylinder by screws 11, the plate thus being suitably tensioned round the cylinder. In a modification, the ends of the plate are not nested but are clamped between two bars, both of which fit into the groove 9 of the cylinder. Co-operating with the cylinder 8 is an impression roller 12, to which a paper or rubber tympan sheet 16 is attached by securing its ends in recesses in a bar 18 held by screws 19 in a groove in the roller. The surfaces of the rollers 8, 12 are spaced apart a distance slightly less than the thickness of the paper to be printed, this being fed mainly by the co-operation of the printing portions of the plate and the impression roller. The paper may be fed into the pass between the rollers by the feed devices disclosed in Specification 446,043 which is referred to. The inking roller 15 is spaced from the printing roller by a distance equal to the thickness of the ink film to be deposited on the printing surface. Specification 7145/89, [Class 100], also is referred to.

Title: An improved method and/or apparatus for filtering liquids
Inventor: ASH JAMES HENRY
Filed: 1951-06-19
Abstract: 713,535. Filters. CARLYLE MANUFACTURING CO., Ltd. Sept. 5, 1952 [June 19, 1951], No. 14561/51. Class 46 An appropriate degree of vacuum in a liquid receiver keeps closed an outlet from the receiver and draws liquid through a filter pad into the receiver, the vacuum being broken down at intervals, thus permitting discharge of the liquid through the outlet, and the filter pads with retained sediment being removed and replaced by unused pads at intervals. Liquid supplied to a funnel 10, Fig. 2, passes through a filter pad held between the lower end of the funnel and a perforate member 9, filtrate being drawn into a vessel 1 by vacuum applied at 13, the vacuum also holding closed a releaser flap valve 2 for discharge of liquid. Where the vacuum source operates continuously, the vacuum in the vessel 1 is relieved by cessation of flow through the member 9 and subsequent passage therethrough of air. Valve 2 is thus automatically released and discharge of liquid occurs through opening 4. Alternatively, liquid will discharge upon removal of the pad and consequent inrush of air, the vacuum being reinstated by substituting a fresh pad. Where pulsating vacuum is applied, liquid discharge occurs during admission of air from the pulsator. The pad is removed after lifting the funnel 10 in the sleeve 12, insertion of a fresh pad being facilitated by an aperture 12a and guides 6b. Alternatively, the funnel and sleeve may constitute a single unit hinged to the lid 6. The pad may be of the type disclosed in Specification 580,162, [Group XX].

Title: Improvements in collapsible slat blinds
IPC: E06B9/302
Filed: 1966-04-01
Abstract: 1,098,328. Collapsible slat blinds. RHEINSTAHL UNION BRUCKENBAU A.G. April 1, 1966 [April 3, 1965], No. 14598/66. Heading E1J. The slats 11 in a collapsible slat blind are connected at each end to adjacent slats by articulated links 2 pivoted to the slats at 4 and to each other at 3 to form an articulated band which is arranged zig-zag-wise as that its joint axes are perpendicular to the window face 5 and are located alternately within and externally of the guide rails 6 of C-section so that as the slats are raised the articulated band collapses concertina-wise and the external joints 4 move along a vertical line 7 whereas the internal joints 3 migrate laterally in the guide rail 6, and the pivot pins 3 co-operate with the flanges 16 of the rail 6 to guide the band and slats and impinge on the flanges 16 to limit the expanding movement of the band 2. The pivot pins 3 are extended and covered by sound damping caps.23 of rubber or plastics and contact the lateral walls of the guide rails to prevent swinging of the blind. Steel or lift bands 10 pass through apertures 14 in the slats which apertures are also lined with sound dampening material 15. The articulated band 2 may be continuous resilient steel or plastics material with the joints formed as bends with guide pins interwoven thereat. The guide rails may be lined with sound dampening material. The slats have a central flat horizontal portion 11 secured to the articulated band 2 and have extending from each longitudinal edge a oppositely uniformly inclined flanges 21.

Title: Improvements relating to the construction of turbine rotors
IPC: F01D5/08
Filed: 1945-06-08
Abstract: 599,829. Gas turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and McLEOD, R. C. June 8, 1945, No. 14632. [Class 110 (iii)] An overhung rotor comprises two bladed discs 13, 16, Fig. 2, and an intermediate unbladed disc 21. The disc 13 has a flanged hub by which it is secured upon the turbine shaft 7. Shoulders 24 on the disc 21 have a shrink fit with annular projections on the discs 13, 16 and the discs 16 and 21 are supported by this means alone. The discs are held together axially by a nut on the extension 15 of the hub of the disc 13 and the construction provides complete annular spaces 18, 20 between the hubs of the discs 13, 16. Toothed flanges 25, 26 on the discs provide driving engagement. The rim of the disc 21 provides a floor 27 opposite the stator blading 6 and this rim may have radial slits as described in Specification 593,918. A rotor may be similarly built up of more than two bladed rotors and the final bladed rotor 42, Fig. 3, may be secured to a tail shaft 46 by means of a ring 47 of triangular cross-section and an annular flange 45 of the rotor 42. The disc 16, Fig. 2, is made selfsupporting in relation to centrifugal load and the discs 13, 16 take part of the centrifugal load of the disc 21. The support afforded to the latter is augmented by off-setting outwardly the mass centres of the discs 13, 16, thereby producing, under running conditions, a centrifugally induced bending moment acting upon the shoulders 24. High-pressure cooling air is led to the hollow shaft 7 and passes through holes 19 to annular spaces 18, 20 and through holes 23 to annular spaces 28, 29. Thence, it passes between the teeth 26 and through channels beneath the blade roots. Cooling air is led also by passages 38 to a space between disc 13 and a stationary wall 33 and from the shaft 7 by passages 19 and 37 to a space 36 between disc 16 and a stationary wall 34. The tail-shaft bearing of shaft 46, Fig. 3, is carried in a housing 41 supported by radial tubes 50 and stiffened by a tubular extension 52 and diagonal struts 53. Cooling air from the hollow shaft 7 passes into the housing 41 and through the tubes 50 and struts 53.

Title: Process and apparatus for the continuous separation of an industrial scale of the constituents of copal
IPC: C09F1/00
Filed: 1962-04-17
Abstract: A process for continuously separating the constituents of copal comprises macerating a mixture of finely divided copal and a liquid phase consisting of water, an acid and a reducing agent, separating free water from the macerated mass, treating it with water or alkali in an amount at least to neutralize the mass, removing occluded water from the water or alkali-treated mass, de-polymerizing the constituents of the resultant water-free mass by heating under reflux, and fractionally extracting the constituents of copal from the product of depolymerization. The process may be carried out in the absence of air and in an inert gas atmosphere (e.g. nitrogen). The acid may be inorganic (e.g. HCl, H2SO4, H3PO4) or organic (e.g. formic, acetic, oxalic), and the reducing agent may also be inorganic (e.g. Al, Zn, NaHSO3, SnCl2) or organic (e.g. acetaldehyde, propaldehyde, butyraldehyde).  The separated constituents include terpenic hydrocarbons, unsaturated non-terpenic aromatic hydrocarbons, oxygenated aromatic hydrocarbons, and vulcanizable distillation residues. Specification 900,621 is referred to.

Title: Pulse generator
IPC: H03K3/64
Filed: 1972-03-30
Abstract: 1371421 Pulse generator INTERNATIONAL BUSINESS MACHINES CORP 30 March 1972 [24 May 1971] 14975/72 Heading H3T In a pulse generator of the type in which an energy reservoir is charged and discharged between upper and lower levels, the upper level is varied periodically with a sawtooth type waveform. As shown a capacitor Cl discharges through a constant current transistor 12 until the voltage at the input base of comparator 14 causes current to flow in transistor 36 of the comparator and switch a bi-stable circuit 16, described below. This renders conducting a transistor 43 to pass a constant charging current of twice the value of the discharge current so that a net charging current equal to the discharge current flows to the capacitor. Charging continues until the voltage at the base of transistor 37 of a comparator 15 switches off transistor 38 and thus the current to the bistable circuit. This restores its original state and restarts the discharge cycle. The resulting pulse output from the bi-stable circuit is amplified at 57. The reference voltage at the right hand base of comparator 15 sweeps upwardly as a capacitor C2 charges causing the amplitude of the sweep voltage generated across capacitor C1 to increase and thus the output pulse width of the circuit to progressively widen. A periodic clock signal at 50 resets the capacitor C1 and C2 to restart the cycles. The reference voltage sweep may be curved upwardly or downwardly (Figs. 2 and 3, not shown) using a non-linear diode or a FET. In addition the two flanks of the sweep across C1 may be of different slope. The bi-stable circuit comprises cross-coupled transistors 39, 40. Setting is effected by passing a current through transistor 36 and resistors 41 and 42 and resetting is effected by interrupting the current through 38 whereby the reduction of current through resistor 42 raises the potential of the base of 39 to reset the circuit.
